Jeremy Pena Injury: On track to return Friday

Pena (rib) will play shortstop in a rehab game with Triple-A Sugar Land on Wednesday and could return from the 10-day injured list Friday for the start of the Astros' series in Boston, Brian McTaggart of MLB.com reports.

Pena occupied the designated-hitter spot for Sugar Land on Tuesday in his first rehab game, going 0-for-2 with a walk and two runs scored. He'll play the field Wednesday, and as long as everything checks out well, he should be activated from the IL on Friday. Pena has been shelved since late June with a small rib fracture.
